Pick several at once. You can add more later.

Your file stays on this device. Nothing is uploaded.

Add your clips, put them in order and get one MP4. Clips of different sizes or shapes are fitted into one frame with black bars, so nothing is stretched. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.

Phones save every take as its own file. Merging them gives you one video to post, send or archive.

How to merge videos

  1. Choose or drop two or more videos on the box above.
  2. Use the arrows to put them in order. Add more files at any time.
  3. Pick the output size and whether to keep the sound.
  4. Press Merge videos and download the single file.

Different sizes and frame rates

The output takes the size and frame rate of the first clip, or 1080p or 720p if you pick one. Every clip is fitted inside that frame. Mixing vertical and horizontal clips works, the narrower ones get bars at the sides.

How long does it take?

Every frame is decoded and encoded again, so merging takes roughly as long as the clips play on a recent laptop, and longer on a phone.

Questions

How many clips can I join?

Up to 50 files and about an hour of total length at a time.

Will clips without sound break it?

No. Silent clips are filled with silence so the sound stays in sync.

Can I add a transition?

Not yet. Clips are joined with a straight cut.
